A novel multi‐target TBD scheme for GNSS‐based passive bistatic radar

IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2497-2512, December 2024.
The paper presents a novel approach to enhance low‐altitude surveillance in urban and suburban areas using GNSS‐based passive bistatic radar systems. Despite challenges such as weak signal power budget and complex multi‐target tracking, the proposed method introduces a track‐before‐detect (TBD) strategy with a DCCF‐based cluster centroid extraction ...

Target detection, ISAR imaging and tracking capabilities of a passive radar net utilising barrage jamming signals

IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2144-2154, November 2024.
This paper demonstrates the possibility of utilising a ground‐based barrage jammer as an illumination source for passive radar detection, tracking and ISAR imaging. This article will present some of the outcomes of field trials conducted within the international electronic warfare exercises.

3-D High-Resolution ISAR Imaging for Noncooperative Air Targets

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article uses the inverse synthetic aperture radar (ISAR) imaging method to present real-world tests on 3-D radar imaging of noncooperative air targets. Initially, the fundamentals of 3-D ISAR are introduced.

Broadband multi‐carrier linear frequency modulation signal reception with subcarrier frequency offset deramp processing

IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2325-2332, November 2024.
The authors propose a multi‐carrier LFM signal reception method based on subcarrier frequency offset deramp processing. By properly introducing a carrier frequency interval difference between the transmit and reference signals, multi‐carrier LFM signal deramp processing is implemented through frequency mixing, which allows crosstalk‐free separation of ...

Measurements and analysis of the radar cross section of chaff dipoles

IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2182-2188, November 2024.
Photo of a filament under test in a stereo‐foam support. Abstract A free space test method to measure the Radar Cross Section (RCS) of single dipole elements is presented. The method is such that dipoles can be measured over a large range of frequencies, in free space and without the need of an anechoic chamber.
